| 81 | Printing apparatus inker with end dams | US338318 | 1989-04-17 | US5003877A | 1991-04-02 | Tadashi Yano; Kenichi Hamada |
| A printing apparatus comprising: a pair of ink rolls (1, 17) defining a nip (2) therebetween; a pair of dams (3, 3') provided in the nip and movable in the direction of the axes of the ink rolls; an ink supplying device having an ink pump (11) for supplying an ink (18) to the segment of said nip located between the dams; an ink recovery device for recovering excess quantities of the ink supplied to said nip; a washing liquid supplying device for supplying a washing liquid (22) to said ink supplying device and to said ink recovering device via said nip; and a lubricant supplying device for supplying a lubricating liquid (8) to the segments of said nip located outside said dams. In printing, the segment of the nip of the ink rolls (1, 17) between the dams (3, 3') is lubricated with the ink film and the segments of the nip of the ink rolls (1, 7) outside the dams are lubricated with the lubricating liquid. The ink or washing liquid remaining in the nip or in the ink circulation path can be forcibly and rapidly recovered and therefore the productive efficiency can be improved. Further, since the ink in the circulation path can be forcibly recovered, the ink will not be present in the ink circulation path when the next order ink is to be circulated in the path, and therefore the problem of the degradation of printing quality due to mixing of one ink and the next order ink in the circulation path can be avoided. | ||||||
| 82 | Washing device for a roller part in a machine unit and the like | US906276 | 1986-09-10 | US4760857A | 1988-08-02 | Noriyuki Shiba; Tomoshi Kawata |
| A washing device is capable of carrying out washing work in a roller part of a machine unit automatically, continuously, concentrically and uniformly. The washing device employs a washing solvent storage tank, and a used washing solvent storage tank,. The device transfers washing solvent in a washing solvent storage tank to a machine unit with a roller to be washed, supplies washing solvent to the roller to be washed set at the end point of the transfer means, a used washing solvent collecting means collects used washing solvent from the proper position of a roller to be washed, and discharges collected used washing solvent to a used washing solvent storage tank. | ||||||
| 83 | Printing press washer | US718238 | 1985-04-01 | US4632030A | 1986-12-30 | William J. Laverick |
| A printing press washer with an elongated tray having a roller engaging wiper blade extending along a front edge for engaging the surface of the lower oscillating roller of an offset lithographic printer, a pair of hanging brackets having hanging hooks for hooking over a transverse tie bar below the ink fountain, and adjusting screws for engaging the frame of the machine for adjusting the wiper blade engagement and pressure on the lower oscillating ink roller of a printing press. | ||||||
| 84 | Washing apparatus for ink rollers of printing machine | US922663 | 1978-07-07 | US4192231A | 1980-03-11 | Yoshito Kawakami |
| An automatic washing apparatus for an inking arrangement is provided. The apparatus comprises a washing vessel which contains a brush device, a washing pipe and a doctor blade. The washing vessel is openable and the doctor blade is moved toward and away from a roller of the inking arrangement. Ink and foreign matter adhered to the roller are removed by the doctor blade. The doctor blade is reciprocated either linearly or circularly so that same is scraped by the brush device, whereby the ink and foreign matter adhered to the doctor blade are washed out. | ||||||
| 85 | Dampener | US610735 | 1975-09-05 | US4036131A | 1977-07-19 | Donald Fenton Elmore |
| A dampener form roll has a wash-up position in which the dampener form roll is in fluid-transferring relationship with the ink form roll so that when wash-up fluid is applied to the ink form roll, it is transmitted to the dampener form roll, and thus effects a clean-up of the ink on the dampener form roll. A throw-off mechanism is provided for moving the dampener form roll between thrown-on and thrown-off positions, and that throw-off mechanism includes a motor having a reciprocating output member connected with a linkage for transmitting the motion of the output member to the dampener form roll. Means is located in the linkage for disabling the linkage so that it is disconnected, thus disconnecting the dampener form roll from the motor. A spring is provided for moving the dampener form roll to its wash-up position upon disconnection of the linkage. Further, the dampener form roll is gear driven through a gear train from the plate cylinder of the printing press and on movement to the wash-up position, one gear for driving the dampener form roll moves out of engagement with its cooperating gear so that the teeth thereof are out of meshing engagement. | ||||||
| 86 | Device for cleaning ink from a printing apparatus | US586568 | 1975-06-13 | US4016812A | 1977-04-12 | David V. Lauk; Lloyd W. Bills |
| A device for cleaning ink from rollers of a printing apparatus. A container of ink solvent is removably mounted to the printing apparatus. A continuous web extends from the container and against the inked roller(s) of the printing apparatus. The web extends into the container and is directed downwardly by additional rollers into the ink solvent. As the printing apparatus roller is rotated, ink is transferred from the roller onto the continuous web. The web is then engaged by two wiper assemblies and a brush assembly thereby cleansing the ink from the web and allowing the ink to be transferred from the web into the ink solvent. | ||||||
| 87 | Dual ink circulation and wash-up system for a press | US563752 | 1975-03-31 | US3974768A | 1976-08-17 | William Grobman |
| A printing press is provided with a dual ink circulation and wash-up system to reduce the wash-up time between color changes. The press includes a fountain and at least one receptacle associated therewith and having at least two compartments. Means are provided to selectively divert liquid from the fountain into one of the compartments while the other compartment is being washed. A plurality of ink supply means are provided for sequentially supplying ink to the fountain. | ||||||
| 88 | Wash-up system for flexographic printers | US44500574 | 1974-02-22 | US3896730A | 1975-07-29 | GARRETT CLYDE BARNER; THAYER WILLIAM STANSBURY |
| A wash-up system for cleaning a flexographic printing system of the type including a pair of ink supply rollers, an ink reservoir, a gravity feed tank for the ink, and a pump in the reservoir for pumping ink to the gravity tank from where the ink flows to the ink rollers. The wash-up system includes suitable apparatus for draining the residual printing ink from the printing system into the ink reservoir, pumping the ink from the reservoir into an ink recovery vessel, directing wash water under pressure to portions of the printing system for cleaning the system, draining the wash water from the printing system into the ink reservoir and then draining the wash water from the reservoir. The apparatus basically comprises a water supply line that branches to various parts of the printing system with appropriate automatically operated solenoid valves for directing the water to portions of the printing system during various controlled phases of the wash-up cycle.

| 89 | Machine for squeeze drying washed ink rollers | US14252971 | 1971-05-12 | US3808966A | 1974-05-07 | BUSCH G |
| A machine for squeeze drying absorbent liners of ink rollers that have been washed previously, said rollers being used in printing presses; where the ink rollers are mounted in multiples on bearing spiders inside a drum having on its interior cylindrical surface spiral drain grooves. The two bearing spiders are rotated and have means to press the ink rollers against the inside of the drum, squeezing the excess washing fluid out of the ink rollers. The excess washing fluid drains into a lower drain area and is then drawn out of the drum by a vacuum suction pump.

| 90 | Inking apparatus having automatic wash-up means | US3800702D | 1972-12-07 | US3800702A | 1974-04-02 | ROBERTS L |
| An inking unit, including an ink fountain formed between an inking cylinder and a scraper type doctor blade, is provided with an automatic wash-up system. The latter includes spray pipes having nozzles that direct cleansing and rinsing fluids against the ink engaging elements. Much of these cleansing and rinsing fluids are recirculated to prevent waste, with recirculating being effected by the same pump that delivers ink to the reservoir from which ink is supplied to the fountain.
